| Research Abstract |
Multiferroic BiFeO_3 has giant dielectric hysteresis at room temperature but very small magnetic hysteresis and so little magneto-electric effect. Then, BiFeO_3 and BiFe_<1-x> M_xO_3 thin films are prepared by pulsed laser deposition under magnetic field and/ or annealed under magnetic field. So, magnetic hysteresis of the prepare thin films could be increased by antiparallel arrangement of different spins of adjacent magnetic ions, defect generation and/ or microscopic texture variation, keeping large ferroelectricity and moreover magneto-electric effect is expected to be enhance.
